Face Detection Project For Beginners | OpenCV Face Detection Mini Project with Code

In this quick video we will be using OpenCV Haar Cascade classifier to build a Face Detection system. You can easily modify the project to detect hands, eyes or build your own custom classifier.

I am really very proud about you since I was searching many explanation nothing is clear but your demonstration made my code successful and very cleanly understood the concept. Thank you so much

[@anukprasad9059]

i'm getting some error after writting the code
please help
descriptor 'detectMultiScale' for 'cv2.CascadeClassifier' objects doesn't apply to a 'numpy.ndarray' object

[@tathagatkumar8705]

My code runs without any errors but the video capture frame is constantly showing as 'not responding'. Could you help me out with that please?

[@SayanNatsu]

In the cap.read() function it is giving me an exception : " unknown C++ exception from OpenCV code"...
Please help

how to used in weapon detection same as face detection please kindly define and which cascade classifier library used both work as well

[@saurabhkalra3042]

can you tell me how to do like this with python:
detect an image on an application and if the image is not there search for the image again
and if it's there then do something.

Well I hav a challenge for you....do exactly the same you did in the video above, but 1) add a centerpoint and 2) have a tracking optical flow line starting from that centerpoint of the bounding box....is it possible???

Pls help me.....it is showing error in the detections=cascade_clasifier.detectMultiScale(frame, 1.3, 5)
And showing cv2.error:opencv(4.4.0)

[@alexandrosaristovoulos4718]

you need to download the haarcascade_frontalface_default.xml from the opencv github: github.com/opencv/opencv/tree/master/data/haarcascades
and add it to the folder where you run your python script

iam getting an error saying gray is not defined how to resolve it??

[@CodeHeroku]

Your variable name should be "frame" not gray.
frame = cv2.cvtColor(frame, 0)
detections = cascade_classifier.detectMultiScale(frame,scaleFactor=1.3,minNeighbors=5)
